Abstract:As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE (HfL) program, the Missouri Department of Transportation (MoDOT) was awarded a $1 million grant to demonstrate the use of innovative technologies for the design-build procurement process. This report documents the contracting method used to encourage contractor innovation and promote fast construction of several bridges, ramps, sound walls, and pavement sections on a 4-mile portion of Interstate 29/35, a six-lane interstate highway in North Kansas City, MO and Kansas City, MO. This project included the construction of the landmark Christopher S. Bond bridge across the Missouri River. This report includes contracting details of the construction project with specifics on steps MoDOT and the contractor took to make timely decisions, minimize project delays, improve safety, and reduce costs, including details on the quality management program, additional applicable standards, and equal or better change proposals. The report also describes the project construction, including safety improvements and steps MoDOT and the contractor took to engage stakeholders. Details of the experiences of MoDOT and the contractor are also included. MoDOT’s overall conclusion was that the project was successful and the agency would use design-build at fixed-cost contracting on future projects when appropriate. Construction costs for the I-29/35 kcICON project would have likely placed traditional delivery and construction methods (baseline) at $23.3 million (low estimate) to $50.5 million (high estimate) more than the as-built case ($232 million). Moreover, delivering the project in only 2.75 years (compared to 8- plus years for traditional methods) saved highway users an estimated $11.4 million in delay costs and $27.5 million in safety costs. Therefore, the estimated total savings from using the innovative HfL project delivery approach range from $62.1 million to $89.4 million. In other words, the innovative approach to this $232 million corridor improvement project had a 27 to 39 percent cost benefit over traditional methods. Highway users also benefited from the increased capacity 5- plus years earlier than if traditional methods were used.
